Well, leave it to brother Rob Kardashian, 29, to propel the Kardashian family name back into the forefront of national consciousness. The usually hapless Rob did so with news that he and his inamorata Blac Chyna had really called an end to their tumultuous relationships.

People on Thursday confirmed that Kardashian and Chyna, 28, have ended their year-long relationship and engagement. “They split a while ago. The wedding plans are off,” a source close to Kardashian told People.

And rest assured, the couple are “both trying to be mature” about their split.

Although the couple attempted to make their relationship work, the insider told People that Chyna became frustrated with Kardashian.

“Chyna is super fed up with Rob and thinks he is way too emotional and depressed,” the insider said. “She thinks he has terrible issues.”

Those terrible issues don’t explicitly include other members of his family, including mom Kris Jenner, sisters Kourtney, Kim and Khloe, or brother-in-law Kanye West.

“He is always battling his own insecurities and is unstable,” the insider said. “It’s a major turn-off to her, and she thinks it’s incredibly unhealthy for the baby and their family.”

Yes, she worries about unhealthy influences on her two children, including her 3-month-old daughter Dream Renee Kardashian with Rob.

This is the same conscientious woman who hooked up with supposedly emotionally unstable Rob in the first place back in January. If you count back the months, it also looks like she got pregnant right away. She then became engaged to him after only three months of dating. Oh, and she agreed to star in a reality TV show with him, “Rob and Chyna,” chronicling their topsy-turvy life together as they prepare to become parents.

Actually, reports that the two split up go back to at least December, when Rob told his Snapchat followers that Chyna had left him, moved out of their home and taken their 1-month-old baby with them.

In recents weeks, the two acted happy in their relationship, and showered their social media feeds with love for one another, People said. They also spent New Years Eve together and celebrated their anniversary with an Instagram video that showed home footage of the couple kissing, cuddling and laughing throughout their short-lived relationship.

But last week, it look like Chyna had already moved on. People reported that the mother of two was seen out to lunch with Jamel Davenport, a guy she was spotted getting close to during a Super Bowl party last weekend. She wasn’t wearing her engagement ring at the party.

“(Rob and Chyna) are living separately, and she’s keeping Rob at arm’s length, both from the baby and from her,” the insider adds.
